Aperture:
The size of the opening in the lens also known as f/stop. (a smaller aperture has a bigger f/stop number--lets in less light) The numbers represent ratios of the lens focal length to opening. The lens focal length is how long the lens is in millimeters. So f/2 is a wider open aperture than f/16 because the numbers are fractions.
Depth of field:
-the range of distance within the subject that is acceptably sharp. The depth of field varies depending on camera type, aperture and focusing distance, although print size and viewing distance can influence our perception of it. It does not abruptly change from sharp to blurry, but instead occurs as a gradual transition.
Shutter Speed: Noise: shutter speed is “the amount of time that the shutter is open”. It is measured in fractions of seconds. The slower the shutter speed the more difficult it is to take a photo without getting photo shake.
Histogram: a very useful tool that many cameras offer their users to help them get a quick summary of the tonal range present in any given image. It graphs the tones in your image from black (on the left) to white (on the right). The higher the graph at any given point the more pixels of that tone that are present in an image.
Burst Mode:
This mode allows continuous shooting, several images can be captured with just one press on the shutter. It is mostly used in mixed light conditions or when the subject is in motion.
White Balance: the reason we adjust white balance is to get the colors in your images as accurate as possible.The basic white balancing settings you’ll find on cameras would usually be: Auto, Tungsten, Fluorescent, Daylight/Sunny, Cloudy, Flash, and Shade.
Self timer:
The self timer gives a delay between the pressing of the shutter release and the shutter firing. It allows photographers to take pictures of themselves, and it is also used to keep the camera held more securely. A common timer is 10 seconds.
Pixels: each pixel contains a series of numbers which describes its color or intensity, The precision to which a pixel can specify color is called its bit or color depth. The more pixels your image contains, the more detail it has to ability to describe.
Auto Focus vs Manual Focus:
Auto focus is a setting on a camera that allows you to choose the picture and the distance, but the camera will focus the lens for you. Manual focus is when the photographer adjusts the focus of the lends by hand. You would want to use manual focus when the object of your image is complex. The object could be moving, extremely close to the camera, or in a low light, which makes it difficult for the camera to focus the lens correctly. If your object is stationary, not complex, or you need your camera to be able to focus quickly, then use the auto focus.
ISO (international standardization organization): ISO measures sensitivity. The lower the number, the less sensitive the camera is to light (use high ISO in darker situations). Also, the lower the number the finer the grain (or the less blur).
File Format: .tiff – This is the best format for printing because it doesn’t lose quality when compressed. It is most commonly used in graphics, imaging software, and publishing industry. .jpeg – This is the best format for the web or small prints. When saving as a “jpeg” the file is compressed causing it to lose some quality. .raw – This format is used mostly by professional photographers because it doesn’t change the file in any way from camera to computer, making it better for manipulating the photos.
